I recently purchased the Zubie Car Hotspot from Verizon that connects to the OBD port on a car. I have mine connected to the Tesla Model X, unfortunately I need the connection to remain always on but the Zubie shuts off after 15 minutes when the car turns off.
Based on my testing, the Zubie will remain powered when the car is charging so perhaps it shuts off based on voltage? Such as when the Tesla DC to DC converter turns on/off?
Do you know if it is possible to keep it always powered? Can I power it externally? If so, which pins?
